标准简介：This International Standard specifies methods for determining the resistance to stable crack extension in terms of crack opening displacement,δ_5,and critical crack tip opening angle,ψ_c,for homogeneous metallic materials by the quasistatic loading of cracked specimens that exhibit low constraint to plastic deformation. Compact and middle-cracked tension specimens are notched,precracked by fatigue,and tested under slowly increasing displacement.
